Is anyone else seeing these, and if so, what are you doing with them?
Seems to be a rather obscure change to the DITA-OT around versions 2.3 or 2.4.
All I've seen so far, for example, are these attributes in table/entry:
<entry ...
dita-ot:morecols="3"
dita-ot:x="1"
dita-ot:y="1">
@dita-ot:morecols seems to be a "helper" companion to @morerows, so that user doesn't have to write programming to convert @namest and @nameend (for the table model HTML uses).
I don't know what x and y do.
Anybody got any insights?
